The cosily niche books and manuscripts market may be about to be hit by one its biggest scandals in recent years. And Paris's Musée des Lettres et Manuscrits, as well as its sister organization the Institut des Lettres et Manuscrits, is in the eye of the storm. 

Le Point reported that on November 18, France's anti-fraud brigade raided the museum and the various branches of Aristophil, a company owned by the museum's founder, Gérard Lhéritier. 

The company is suspected by the tax authorities and Tracfin—a public body fighting money laundering and terrorism financing—of “deceptive marketing practices," and “gang fraud." At time of writing, the Aristophil website as well as the websites for the museum and the institute appear to have been taken offline.
